Most of us doing this challenge has found our passion in writing. My passion is to help others find peace after dealing with trauma or giving tools for them to deal with life.
What happens if you're not sure you have found your passion?
Start thinking about things that make you happy. Make a list. Investigate. What can you do for hours and time flies? Don't interfere with this and try and manipulate the findings. It will delay you. Ride it out and see what happens. Maybe you have a passion you've never thought about.
